“…The same trend was noticed at 28 days. Similar findings were reported by [38,39]. The decrease in strength with the marble dust is because the surface is smooth, which can cause a lack of adhesion between the particles and cement paste [8,40].…”

Nowadays, the development of infrastructure is in full swing, which exploits natural resources and causes environmental pollution. Furthermore, cement is the most essential commodity for construction material mainly concrete, and its production is rapidly increasing to fulfil the demand for construction. The cement production is regarded as the one of the key causes of CO2 emissions, which adversely affect the atmosphere by causing global warming. In addition to this, the ecosystem may suffer from marble quarrying and construction material processing. Nonetheless, waste marble can be used as a by-product if managed in accordance with regional, national, and international environmental laws. On the other hand, Currently, LD slag is disposed of in landfills, which exacerbates the scarcity of available land and contaminates groundwater through the leaching of heavy metals. The waste materials have the potential to be used in the development of infrastructure materials. The infrastructure development has aggravated the issue of rainwater runoff and flash flooding in rainy seasons because of inappropriate drainage. The elimination of sand in pervious concrete reduces its strength performance its practical applications are still limited. This study is aimed toward the permeability improvement of conventional pavement concrete by the implementation of pervious concrete and also to improve its strength characteristics. In this study, an attempt has to be made to replace the cement with marble dust up to a replacement level of 0% to 20% with an interval of 5%. Also, natural aggregate is replaced with Linz-Donawitz (LD) slag by 5%, 15%, 25%, and 35%. From the study, it is found that the use of marble dust and LD slag improves the strength properties, but reduces the permeation properties.

“…The durability of the mixture using waste marble powder with varying percentages exhibits a minor improvement in comparison to the control mixture. Kumar & Kumar (2015) conducted a study on the partial substitution of cement with marble dust powder. The study involved casting M25 grade concrete according to the Indian Standard (IS: 10262-2009).…”

All across the world, concrete is the most often used construction material. Many different building applications use concrete as their main material. Were strength, durability, impermeability, fire and abrasion resistance are required, this is the material of choice. Determine the compressive, split tensile, and flexural strengths of a concrete mix with M25 grade is the main goal of this work. In addition, Marble Dust (MD) and Micro Silica (MS) are used in part place of cement in the research. Our study covers the process of Tertiar Blending cement with Marble dust (MD) and Micro Silica (MS). Substances call Supplemental cementitious materials (SCMs) are added to concrete to increase its durability and strength. Significant advances in the concrete industry have come from the application of SCMs, including resource conservation, environmental preservation, energy and cost reductions. Use of surplus materials can result in less cement being used. Significant study has been done on using marble dust and micro silica in place of cement, and the results have shown to be good for strength and durability. Currently used, tertiary blending is the process of combining cement with two Supplementary Cementitious Materials (SCMs) to improve concrete performance. However, by utilizing a quaternary blend, which can better optimize the properties of concrete, there is possibility for further improvements. The aim of this work is to develop a mixture design for Tertiary Cement Concrete that uses industrial waste products, marble dust and micro silica, as Supplementary Cementitious Materials. The objective is to assess, using water to cement ratios of 0.40, the mechanical characteristics of concrete with a grade of M 25 in moderately exposed situations. Ten combinations in all were made, with different amounts of marble dust (MD) and micro silica (MS). Three groups were formed out of the mixtures, with 6%, 7%, and 8% of Micro Silica (MS) kept constant with MD variances ranging from 5% to 15%. The compressive strength of the concrete mixes including Tertiary mixing—was assessed seven and twenty-eight days after curing. Using 0.6% of Super Plasticizer in the mixture has shown that fresh concrete is workable within the 110–140 mm slump value range. The slump value has been found to reach 140 mm for the combinations with lower blending percentages and a 0.4 water-to- cement ratio. The density of the just mixed concrete is then measured and compared to the density attained after 28 days of curing. Combining 5% Marble Dust (MD) and 8% Micro Silica (MS) with a 0.40 water-to-cement ratio (W/C) produced the best compressive strength. Compressive strength significantly decreased at all phases of growth when Micro Silica was substituted at a rate of 6 to 8% and Marble Dust at a rate of 10 to 15%. Therefore, the concrete mixture including 5% MD and 8% MS replacement can potentially yield superior outcomes, making it a viable and fitting material for rigid pavement.

“…Marble powder is produced during the cutting and polishing processes of marble blocks. It was reported that around 20% to 25% of waste marble powder was produced during marble manufacturing processes [33][34][35][36]. The generation and deposition of these wastes in open landfills may lead to serious environmental and public health threats.…”

In masonry construction, the most commonly used building unit all over the world is the burnt clay brick. Adding waste materials in certain percentages to these bricks helps in eliminating the environmental burden occurring in the form of excessive waste accumulation on open land sites, leading to sustainable and economical construction. This research program aimed to examine the feasibility of using waste marble powder (WMP) and sugarcane bagasse ash (SBA) in the manufacturing of clay bricks. WMP was collected from local marble cutting workshops, whereas SBA was prepared by burning the waste sugarcane obtained from various sugar mills in the local area. Brick specimens incorporating 5%, 10%, 15%, and 20% of hybrid WMP and SBA were prepared at a local brick kiln. Burnt clay bricks were transported to the laboratory, and their mechanical and durability properties were evaluated. A reduction in weight per unit area of brick specimens incorporating waste materials was observed, allowing them to be easily handled and transported. Decreased compressive strength was due to the addition of waste materials in comparison with conventional clay bricks. However, waste percentages up to 15% satisfied the criteria for the minimum compressive strength as per the Building Code of Pakistan (BCP). All tested samples showed flexural strength greater than 0.65 MPa. Tested bricks incorporating 10% and 20% of waste materials had water absorption values of 18% and 21%, respectively, which are higher than that of conventional clay bricks. Moreover, bricks incorporating waste materials exhibited a higher initial rate of absorption than conventional clay brick; therefore, such bricks need to be wet well before use in masonry construction. Brick specimens showed less than 1% weight loss, and bricks exhibited no signs of distress and cracking after 50 freeze-thaw cycles. A decrease in compressive strength was observed due to sulphate exposure. However, specimens with 10% waste materials still satisfied the minimum compressive strength requirement of BCP. Based on this study, it can be concluded that bricks with up to 10% hybrid waste materials (WMP and SBA) will assist in the environmental issues of these wastes, leading to more sustainable and economical masonry construction.
